feat: Enable configuration of the OpenIdmetadata's refresh interval

[ceciliaavila]

#minor

Description

This PR adds the tokenRefreshInterval property to the ConnectorClientOptions interface to set up the interval in the bot's configuration. This value is used in OpenIdMetadata's getKey method to retrieve the key from the cache, or to make a new request.

The interval should be configured in the following way:

const botFrameworkAuthentication = new ConfigurationBotFrameworkAuthentication(
    process.env,
    undefined,
    undefined,
    undefined,
    { tokenRefreshInterval: 1 } // Set the token refresh interval to 1 hour.
);

const adapter = new CloudAdapter(botFrameworkAuthentication);

Considerations:

• If tokenRefreshInterval is not set, it defaults to 24 hours (as it was originally).
• If tokenRefreshInterval is set to 0, it refreshes the token for each request.
• If tokenRefreshInterval is set to a value, e.g. 1, it refreshes the token after an hour.

Specific Changes

• Updated ConnectorClientOptions interface to include the tokenRefreshInterval property.
• Updated OpenIdMetadata class to receive the interval in the constructor and use it in the getKey method.
• Updated JwtTokenExtractor to pass the value of the interval to the OpenIdMetadata class.
• Updated ParameterizedBotFrameworkAuthentication to pass the value from the options to the JwtTokenExtractor instances.
• Added 2 new unit tests in openIdMetadata.test.

Testing
